SST product


A sea-surface temperature (SST) product was used for the spatial analysis of marine heatwaves (MHWs) at the surface of the Mediterranean.

MHW


“A prolonged discrete anomalously warm water event that can be described by its duration, intensity, rate of evolution, and spatial extent.” (Hobday et al. 2016)

Metrics

See Table 2 in Hobday et al. (2016) for a full list of metrics.

  • Count (n): The number of discrete events in a period of time
  • Duration (days): The number of days a single event lasts for
  • Mean intensity (°C): The average temperature anomaly during an event
  • Maximum intensity (°C): The highest temperature anomaly during the event
  • Cumulative intensity (°C days): The sum of the temperature anomalies
  • Rate onset (°C/day): Daily increase in temperature from start to peak of event
  • Rate decline (°C/day): Daily decrease from peak to end of event
